Subject: [Bug 198511] lags in youtube videos 1080p 60fps with radeon hd4650 and kernel 4.15rc8
Date: Sat, 20 Jan 2018 04:11:52 +0000	[thread overview]

--- Comment #12 from Barto (mister.freeman@laposte.net) ---
Created attachment 273757
  --> https://bugzilla.kernel.org/attachment.cgi?id=273757&action=edit
workaround by reverting changes made by the bad commit

I created a patch, it's a workaround very simple, 

it reverts changes made by commit 648bc3574716400acc06f99915815f80d9563783
related to drm/ttm and radeon_ttm.c,

the idea is to restore the same behaviour of kernel 4.14.13 for drm/ttm, 

8 files patched :

drivers/gpu/drm/ttm/ttm_bo_util.c
drivers/gpu/drm/ttm/ttm_memory.c
drivers/gpu/drm/ttm/ttm_page_alloc.c
drivers/gpu/drm/ttm/ttm_page_alloc_dma.c
drivers/gpu/drm/radeon/radeon_ttm.c
include/drm/ttm/ttm_debug.h
include/drm/ttm/ttm_memory.h
include/drm/ttm/ttm_page_alloc.h

I hope a definitive solution will be found by Alex or Christian König
